COMBlNED WATER HEATER AND PURIFIER.

SPECIFICATION forming part of Letters Patent NO. 555,155, dated February25, 1896.

Application filed September 18, 1894, Serial No. 523,362. (No model.)

To whom it may concern.-

Be it known that I, THOMAS GUNNING, a citizen of the United States,residing at Pittsburg, in the county of Alleghenyand State ofPennsylvania, have invented certain new and useful Improvements in aCombined ater Heater and Purifier; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse the same, reference being had to the accompanying drawing, whichforms a part of this specification.

My invention relates to an improved waterpressure heater and purifier;and it consists in certain details of construction and combination ofparts, as will be fully described hereinafter.

In the accompanying drawing the figure is a side sectional elevation ofmy improved C0111- bined water heater and purifier, which is constructedand arranged in accordance with my invention.

To put my invention into practice I provide a shell or casing 1 of acylindrical form and a suitable size, having a rounded base 2 and fittedat the top with a cap or cover Arranged within this casing 1 isacylindrical chamber 1, having an open base some distance above thebottom of the casing 1, and fitted at the top with a covering 6, whichis supported by means of a bolt 7 or other suit able means, whereby anannular space is left, as at S, to permit the steam to enter into thecompartment at, as will be hereinafter described. Attached to theoutside of this interior shell at are a number of radial projectingstuds or arms 5, adapted to receive and collect the sediment from thewater entering through the pipes f) and 10. The pipe 9 en tering the topof the device is for the purpose of conducting the water and steam fromthe exhaust-heater common to all boilers or steam genera-tors, and thepipe 10 is for conducting steam from the boiler to the combined heaterand purifier. Entering beneath the inner compartment l is a pipe 1iwhich projects upwardly and is bent in the form of a gooseneck and isadapted to feed water to the boiler, and is also provided with a valveor cock to regulate and control the flow of water to the same.

Arranged at the bottom of the combined heater and purifier is a conicalbase 16, having an opening through the same to form a compartment 17 tocollect the mud or other sediment from the water and steam enteringthrough the pipes 9 and 10. Connected to the base of the shell 1 is ablow-ofi pipe 18, used for the purpose of cleaning the device, andarranged above the said pipe is a conical or funnel-shaped portion 16,which will permit the sediment to pass through the same and collectwithin the compartment 17 and be blown off through the discharge-pipe 18when cleaning the apparatus.

Suitable manholes or openings 19 at the bottom and at the top 20 areprovided for the proper working ofthe apparatus.

In operation the water and steam from the exhaust-heater is entered intothe apparatus through the pipe 9, and a steam-jet from the boiler isentered through the pipe 10. The steam and water from the pipes 9 and 10will condense on the top of the dome 6 and are converted into water, andthe diameter of the dome 6 being larger than the flange beneath the saidcondensed water will fall, while the steam not condensed will enter intothe chamber i and serve to heat the water therein. The water fallingfrom the flange or periphery of the dome 6 will deposit its impuritiesupon the rough projecting radial parts 5, and any impurities left in thewater will settle upon the conical base 16 and be discharged into thecompartment 17. lhe steam and condensed water from the exhaust-heaterentering the apparatus through the pipe 9, together with the live steamfrom the boiler through the pipe 10, will raise the temperature withinthe heater to about 315, and this temperature will cause any impuritiesin the water to settle and be deposited into the funnel 16, and fromthere into the compartment 17, and be blown off through the pipe 18. Theprojecting arms 5 will gather any sediment deposited upon the same, andthe apparatus is cleaned when desired by removing the manhole 20 andintroducing a stream of water to wash the several parts of theapparatus.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The combined water heater and purifier,

comprising the outer chamber having steam and water inlet-pipe, and ajet-pipe entering the same, and the inner chamber with araised topproviding steam-ingress passage between it and the upper end of saidinner chamber, a boiler water-feed pipe extending through the outerchamber and having its inner gooseneck end extending up into the loweropen end of the inner chamber, said inner cham- 1o ber having upon itsouter side sediment-c0l hereunto aflix my signature this 31st day of I5August, A. D. 1894.
